Abstract

The rock drill apparatus ( 1 ) comprises a rock drill machine ( 6 ) provided with a percussion device ( 4 ), a feed device ( 9 ) and a tool ( 7 ), the tool ( 7 ) end comprising a bit ( 8 ) for breaking rock. The tool ( 7 ) is arranged to transmit impact energy generated by the percussion device ( 4 ) as a compression stress wave to the bit. The feed device ( 9 ) is arranged to thrust the tool ( 7 ) and the bit ( 8 ) against the rock to be drilled, whereby on drilling at least part of the compression stress wave generated by the percussion device ( 4 ) to the tool ( 7 ) reflects from the rock to be drilled back to the tool ( 7 ) as tensile stress, and impact energy of the percussion device ( 4 ) is adjusted on the basis of the level of tensile stress (sigma<SUB>v</SUB>) reflecting from the rock.
